VALVE.

Specification of Letters Patent Patented Mar.25,113.

Application fiIedDecember 10, 1910. Serial No. 596,573.

The principal objects of this invention are to provide an etlicientvalve of simple construction, having means which is not only operativeto selectively control its different ports, but which is arranged tocontemporaneously open said ports to divide the fluid passingtherethrough, or to mix two fluids, depending upon the direction of fiowthrough the ports of said valve, and to provide a valve wherein theoperative parts he readily assembled and replaced.

The term of this invention hereinafter described, provides a threeportvalve, with a stem carrying a valve plug operative to control two csaid ports, and a disk gate movahle with said plug and operative tocontrol the other port.

This invention is advantageous in that it provides a valve having aplurality of ports with a single valve stem having means 0perative tocontrol all of the ports contemporaneously, whereby two ports may bemaintained completely open to permit the unrestricted passage of fluidthrough the valve, while the other port may he opened and closed, or itsarea varied by said means without restricting the flow through said openports, or may he actuated to etl'ect the contemporaneous control of twoof said ports, to effect the opening of one while closing the other, andsaid means may be further actuated to completely close or open all ofsaid ports.

This invention includes all oil'- the various novel features ofconstruction arrange ment hereinafter more definitely specified.

In the accompanying drawings, Figure 1 is a central verticallongitudinal sectional view of a valve constructed in accordance withthis invention; Fig. 2 is a plan sectional view of the valve shown inFig, 1 taken on 12 in the casing 7 to permit vides the ports 8 and 9which are arranged to be controlled by the valve plug 10, and the port12 which is arranged to be controlledby the disk gate 13 which ismounted for rotation between the casing 7 and the plate It, having theoutlet nipple 15 in alinement with said port 12.

The plug 10 preferably comprises the cylindrical segment which is fittedin the cylindrical chamber 17 and which has the extended lugs 18respectively fitted to, and embracing the squared region 19 of the valvestem 20, and is maintained in operativeposition against the cylindricalwall of the chamber 17 by the spring 21, preferably formed of anon-corrodilole material, such for instance, as. phosphor bronze. Saidplug 10 may be rotated to control either of the ports 8 and 9 by therotation of the valve stem 20, which extends through the stulling her:22 in the casing 7, and which is conveniently provided with the handle 2rdisposed exterior to said casing.

As best shown in Fi 3, the lower end of the stem is provided, adjacentto the squared region 19, with the squared region 25 upon which the gate13 is mounted and the reduced trunnion 26 which latter is convenientlseated in a recessed bearing 27 provide therefor in the plate 14h Thegate 13 has its periphery 28 chamlered to fitthe seat 29 in the plate 14to prevent the leakage into the outlet nipple 155, and said gate 13 isarranged to he maintained upon its seat in said plate 12 by the spring30 which is also mounted on the squared region 25, and bears against theshoulder 31 between the respective squared regions 19. and 25 of saidstem. The gate 13 is provided with the arcuate aperture 32 which isarranged to regist-erwith the port fluid through said port 12 and nip le15, as shown in Fig. 2, and to maintain this port 12 open duringsubstantially a quarter rotation of the plug 10 in the direction ot' thearrow indicated in said figure.

Referring againto Fig. 2 of the drawing,

the passage of it will be-seen that by the movement of the segmentalplug 10 approximately 90 from the position shown in said figure in thedirection of the arrow indicated thereon, a free passage will beefiected, not only through theports 8 and 9, but through the port 12which will be maintained open during said movement of the gate 13 by itsarcuate or elongated aperture 32; by a further rotation of said plug 10and gate 13 to a position substantially 180 from the position shown inFig. 2, all of the ports of thevalve will be closed; by rotation of theplug segment 10 and the gate 13 to a position approximately 270 from theposition shown in Fig. 2 in the direction of the arrow, the ports 8 and9 will be wide open, and the port 12 closed; and by the movement of theplug and gate from the position shown in Fig. 2 in opposition to thearrow in Fig. 2, the relative areas of the ports 8 and 12 may be variedinversely.

It will be seen that the valve above described is effective to dividethe fluid passing from the pipe 34 and direct it through the respectiveports 8 and 12 in, any desired proportions, or to selectively directsaid flow through either one of the ports 8 and 12 as desired. It isequally obvious that said valve'may be utilized for mixing differentfluids by reversing the direction of flow therethrough and connectingthe respective ports 8 and 12 withpipes conveying different fluids andcontrolling their flow in any desired proportions through the port 9 andinto the pipe 34.

It is not desired to limit this invention to the precise details ofconstruction and arrangement as herein set forth, as it is obvious thatvarious modifications may be made therein without departing from theessential features of the invention as defined in the appended claims.

Having thus described my invention, I claim:
